HYPODERMIC cAsE.

T 0 all whom it may concern:

Be it known that I, GEORGE E. ELVVELL, a citizen of the United States,and residing at Boston, county of Suffolk, State of Massachusetts, haveinvented an Improvement in Hypodermic Cases, of which the followingdescription, in connection with the accompanying drawing, is aspecification, likev characters on the drawing representinglike parts.

This invention relates to a pocket case for holding and carrying ahypodermic syringe and a set of vials containingvarious liquids for usein connection with the syringe.

The object of the invention is to provide a case of this type, compactin form, light in face without additional support, thus hold ing thevials and syringe in such position that either or all may readily beremoved therefrom, as required.

A further object of the invention is to provide a construction in which,when the a case is in open position the compartments containing theVials will be laterally open, exposing the vials throughout theirlength, thus enabling the labels upon the vials designating the contentsthereof, to be in full view preventing mistakes as to the contents, andenabling each to' be readily identified.

A further object of the invention is to provide a case of this type inwhich the syringe itself locks the case in closed position by a simpleengagement therewith of its "usual transverse finger piece, and in whichupon the removal of the syringe the case opens automatically, preferablyby the use of a spring construction.

These and other objects of the invention will more fully appear fromtheaccompanying description and drawings, and will be particularly pointedout in. the appended claims.

Referring to the drawings in which'I have illustrated a preferred formof my invention, Figure 1 is a Side view of my improved case, the partsbeing shown in closed position. Fig. 2 is a longitudinal section,

the parts being shown in the same position; Fig. 3 IS a transverseSGCtlOIl taken on the pair of centrally pivoted sections each sec-.

tion presenting oppositely extending wings. One section is shown asconsisting of a central tubular member 1, a base plate 2, and oppositelyextending wing members 3 and at. The other section consists of atopplate 5 and oppositely extending wing members 6 and 7. This section ispivotallymounted on the tubular member 1 of the first section and issoconnected thereto that a limited longitudinal movement is possible. Thebase and top plates are circumferentially flangedas indicated at 8 and9. The lower ends of the wing members 3 and i are positioned within theflange of the base plate 2 and soldered thereto, and the upper ends ofthe wing members 6 and are similarly se-.

cured to the top plate. f

Thefree ends .of the wingmembers are adapted to be received within theflanges of the opposed top plate and base plate when the case is closed,thus interlocking the sec tions. The aforesaid longitudinal movementtherefore serves to interlock and to release the sections. I provide forthusinterlockingtheparts order to make the case more rigid andsubstantially dust proof so that 'it may more safely be carried loose inthe.

pocket.

Each wing member is corrugated in an manner to present recesses orpockets 10 in one face. I prefer this corrugated shape as it is strongand conveniently manufactured and provides a simple method of formingthe compartments. Thetwo wing members ofeach section are so positionedthat the recesses are presented on "opposite sides of the section andthe wing members of the two sections are reversely arranged so that therecesses are presented toward each-other and thus cooperate to providevial compartments. Each wing member is provided at its inner edge with aring 11 embracing the tubular Lmember. The rings of the members 3 and 4are preferably soldered to the tubular member, but the rings of themembers 6 and 7 are freely rotatable thereon.

The recesses or pockets of wing members 3 and 4 are provided withretaining Springs 12 to retain vials or the like in position.The'central tubular member besides acting as the pivot member of thecase presents a cellular compartment adapted to receive the barrel of ahypodermic syringe 13. This tubular member extends above the rest of thecase and is provided with L-shaped slots 14, with which the finger piece15 of the syringe cooperates to form a bayonet oint holding the syringein. position. The inner ends of the slots may be formed to provideretaining notches 16 to prevent accidental rotation of the syringe. Thebayonet slots 14 are so positioned that thefinger piece 15,-

when in position in the inner ends of the slots, may lie longitudinallyof and in contact with the top plate of the pivoted section to hold thesections in closed and inter locked position. A spring 17 is mounted inthe'tubular member and acts to automatically open the case.

' One end of the spring is secured in the base plate as indicated at 18and the other end extends through an L-shaped slot 19 in the side of thetubular member and is secured to the pivoted member as indicated at 20.The slot 19, cooperating withthe spring determines the path of movementof the pivoted section. The longitudinal portion of the slot permitslongitudinal movement of this section to interlock and release the partsand the transverse, portion permits swinging movement to open and closethe case. The spring 17 is tensioned in two directions so that it tendsto move the pivoted section longitudinally and rotatably to I openposition.

The four wing members are shown as of similar shape and when so made mayall be stamped from sheet metal by using a single set of dies. The rings11 may conveniently be formed integral with the wing members by stampingthem out in the plane of the members, as shown in Fig. 5, and afterwardtwisting them through an angle of 90. In order that the edge of the wingmembers may lie close to the tubular memberand form a tight joint, therings are set back into vrecesses as indicated at 21 in Fig. 5. Whentwisting therings one ring of each section is moved slightly upwardlyand the other similarly downwardly so that the wing members willproperly mate.

. Ihave illustrated and described one practical embodiment of myinvention. The invention, however, is notlimited to the constructionshown as'it will be obvious to one A skilled in the art that variousmodifications may be made without departing from the spirit of theinvention.
